generic: Doper
for me only: Pirate!
borrowed from zut in a threat in ATMB about the number of active posters:
Doperous doperous ubiquitous for generic high post count dopers.
and
Doperous doperous hensteethius for generic low post count dopers.
I think there should be a third category for people who aren’t truly low or high, but I’m not creative enough to think of one.
Title either just for me or for other really low post count long term members: perpetual wallflower.
